Skip sparse runs when collecting /var/log/lastlog in acquire
Similar to how the usnjrnl is collected.
Would no longer be an issue with ASDF.
Can confirm this is still an issue. Encountered various /var/log/lastlog sparse files that the tarfile library apparently can't write to an archive, even when selecting the GNU_FORMAT:
From https://docs.python.org/3/library/tarfile.html
The GNU tar format (GNU_FORMAT). It supports long filenames and linknames, files bigger than 8 GiB and sparse files. It is the de facto standard on GNU/Linux systems. tarfile fully supports the GNU tar extensions for long names, sparse file support is read-only.
Meaning that in our case, some Acquire .tar.gz files expand from ~800MB to ~450GB .tar files, which is not really what we expect and want.
